flattenArrayWithUnflattened.test            - never terminates
caseVariations.test                         - see #1700
caseWithGroup.test                          - works only for CO, according to Emrys "Nightmarish QScript (just enormous)"
doubleFlattenWithIntervening                - same as marklogic "doesn't preserve the fact that the first element doesn't have the req field, so missing NA in result"
null/nullTestExprs                          - same as marklogic, JVM OOM error
null/nullTestExprsWithMissing               - same as marklogic, JVM OOM error
symmetricNonJsJoinCondition                 - same as marklogic, QScript never finishes
temporal/datePartsConverted.test            - never terminates
unifyFlattenedFields.test                   - never terminates, simpler version 'select loc[*] from zips` works
unifyFlattenedFieldsWithMultipleUses.test   - same as above
unifyFlattenedFieldsWithUnflattened.test    - same as above
fakeObjectId.test                           - looks like mongo specific
it/src/main/resources/tests/joins/*.test    - all self-joins are currently not working
nonJsJoinCondition.test                     - same as above
multilineLike.test                          - all queries using `LIKE` are broken
flattenGroupedObject.test                   - all queries using `LIKE` are broken
filterSortLimit.test                        - all queries using `LIKE` are broken
projectIndexFromGroupWithFilter.test        - all queries using `LIKE` are broken
likeWithConstantFoldablePattern.test        - all queries using `LIKE` are broken
multistageFlatten.test                      - all queries using `LIKE` are broken
likeWithConstantFoldablePattern.test        - all queries using `LIKE` are broken
different-flattens.test                     - all queries using `LIKE` are broken
multitypeFlatten.test                       - all queries using `LIKE` are broken
skipCount.test                              - submitted as bug https://github.com/quasar-analytics/quasar/issues/1748
citiesByLargestZip.test                     - sort order is not maintained by `reducedByKey` which is called because of "distinct city"
shortCities.test                            - sort order is not maintained by `reducedByKey` which is called because of "distinct city"
LocationCount.test                          - runs but gives empty result, same thing in Marklogic, maybe problem is not in connector?
